templater: allow piping generator-type function output to filters
Template functions use "yield"s assuming that the result will be combined
into a string, which means both "f -> str" and "f -> generator" should behave
in the same way.
Before this patch, piping generator function resulted in a cryptic error.
We had to insert "|stringify" in this case.
$ hg log --template '{if(author, author)|user}\n'
abort: template filter 'userfilter' is not compatible with keyword
'[(<function runsymbol at 0x7f5af2e8d8c0>, 'author'),
(<function runsymbol at 0x7f5af2e8d8c0>, 'author')]'
